Fault Code Description Definition
P0112
Air intake temperature sensor sig-
nal voltage is too low
The air intake temperature sensor is integrated in the
engine air intake pressure and temperature sensors to
measure the temperature of the air that goes into the
engine. ECM internal pressure regulator circuit provides
5V reference voltage to terminal 2 of intake pressure and
temperature sensor wiring harness connector E12
through terminal 42 of ECM wiring harness connector
E01. The air intake temperature voltage - drop signal can
be obtained in this circuit. Place terminal 1 of intake pres-
sure temperature sensor E12 on low potential by terminal
17 of E01.
P0113
Air intake temperature sensor sig-
nal circuit voltage is too high
